摘要

Coexistence of moyamoya disease (MMD) and subclavian steal syndrome (SSS) is an extremely rare condition. We here presented the imaging features of a 50-year-old male with complaints of the severe headache and left upper limb weakness. Computed tomography (CT) angiography showed steno-occlusion of the right terminal internal carotid artery (ICA) and left middle cerebral artery compatible with MMD and total occlusion of the left proximal subclavian artery. Phase-contrast (PC) magnetic resonance (MR) angiography and Doppler ultrasonography (DUS) demonstrated retrograde flow pattern in the left vertebral artery.
